Description

Technical Field

[0001] This utility model relates to the field of gas cylinder drying technology, and in particular to a seamless gas cylinder vacuum drying device. Background Technology

[0002] Gas cylinders are containers used to store gases and are commonly found in various fields such as industry, laboratories, medical facilities, and homes. Gas cylinders are typically made of steel or aluminum and are designed to withstand high pressure. Depending on the type of gas used, gas cylinders can be classified into several types, such as oxygen cylinders, argon cylinders, hydrogen cylinders, and liquefied petroleum gas (LPG) cylinders. The use of gas cylinders has certain requirements, such as the need for cleaning to ensure the cleanliness of the inner and outer walls; and the need for pressure testing to ensure proper functioning. After cleaning or pressure testing, water droplets may remain on the inner and outer walls of the cylinder; therefore, the cylinder needs to be dried to ensure its proper use.

[0003] Currently, gas cylinders are generally dried using vacuum drying equipment. In use, the cylinder is placed inside the equipment, and then dried by heating and creating a vacuum. However, most current vacuum drying equipment lacks a designated placement structure for the cylinders. Users must manually determine their location and arrange them, which is inconvenient. Furthermore, the lack of a placement structure increases the risk of cylinders tipping over during placement.

[0004] A vacuum dryer is disclosed in utility model application number CN202222302885.3 and publication number CN218034032U, belonging to the field of dryer technology.

Detailed Implementation

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example:

[0030] like Figures 1 to 2 As shown, in order to solve the above problems, this embodiment discloses a seamless gas cylinder vacuum drying device, including a vacuum drying device body 10 and an installation component 20. The vacuum drying device body 10 is mounted on the installation component 20, and a drying chamber 100 is provided inside the vacuum drying device body 10. A sliding placement component 30 is provided inside the drying chamber 10.

[0031] The sliding placement assembly 30 includes a sliding structure 300 and a placement structure 301. The sliding structure 300 is disposed at the bottom of the drying chamber 100, and the placement structure 301 is disposed on the sliding structure 300. The sliding structure 300 is used to realize the movement of the placement structure 301.

[0032] The placement structure 301 includes a mounting frame 302 and a fixing frame 303. The mounting frame 302 is provided with a plurality of placement areas 304 for placing gas cylinders. The fixing frame 303 is mounted on the mounting frame 302 and is detachably connected to the mounting frame 302. The fixing frame 303 is provided with a plurality of limiting rings 305 that cooperate with the placement areas 304. The limiting rings 305 are located above the placement areas 304 and cooperate with the gas cylinders.

[0033] In use, this invention first places the fixing frame 303 on the mounting frame 302, so that the limiting ring 305 engages with the placement area 304. Then, the bottom of the gas cylinder passes through the limiting ring 305 and is placed in the placement area 304 on the mounting frame 302, thus achieving placement and positioning of the gas cylinder. Simultaneously, this invention, through the provision of a sliding structure 300, allows the placement structure 301 to be movable, facilitating the placement of the gas cylinder on the placement structure 301. Compared to traditional gas cylinder vacuum drying equipment, this invention, by setting up the mounting frame 302 and the fixing frame 303, solves the problems of current gas cylinder vacuum drying equipment requiring manual positioning and arrangement, which leads to inconvenience, and the potential for the gas cylinder to tip over during placement.

[0034] It should be noted that the inner diameter of the limiting ring 305 needs to be set according to the diameter of the gas cylinder body. In order to accommodate more gas cylinders, multiple fixing brackets 303 can be set, and different fixing brackets 303 can be equipped with limiting rings 305 of different inner diameters, so as to accommodate more gas cylinder drying.

[0035] like Figure 1 As shown, in order to install the vacuum drying equipment and facilitate the drying of gas cylinders, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the main body 10 of the vacuum drying equipment includes a drying chamber body 101 and a vacuum pump 102. The drying chamber 100 is set inside the drying chamber body 101. The vacuum pump 102 is set on one side of the drying chamber body 101 and is connected to the top of the drying chamber body 101 through a connecting pipe 103. The connecting pipe 103 communicates with the drying chamber 100. The installation component 20 includes an installation cabinet 200 and an installation bracket 201. The drying chamber body 101 is set on the installation cabinet 200. The installation bracket 201 is set on the installation cabinet 200 and is located on one side of the drying chamber body 101. The vacuum pump 102 is set on the installation bracket 201.

[0036] During use, the gas inside the drying chamber 100 can be extracted by the vacuum pump 102, thereby creating a relative vacuum environment inside the drying chamber 100, which facilitates and accelerates the drying of the gas cylinder.

[0037] The drying oven body 101 can be a single-door vacuum drying oven that can achieve the function of this utility model in the prior art, and the vacuum pump 102 can be a vacuum pump 102 that can achieve the function of this utility model in the prior art.

[0038] like Figure 3As shown, in order to facilitate the placement of gas cylinders, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the mounting frame 302 includes a placement plate 306 and a pair of support parts 307. The placement plate 306 is disposed between the pair of support parts 307. The two sides of the placement plate 306 are respectively fixedly connected to the bottom of the pair of support parts 307. A plurality of placement areas 304 are disposed on the placement plate 306. The placement plate 306 is provided with a separator 308 for dividing the placement plate 306 into a plurality of placement areas 304. The separator 308 is fixedly connected to the placement plate 306.

[0039] When in use, the bottom of the gas cylinder can be placed in the placement area 304 by passing through the limiting ring 305, thereby completing the placement and fixing of the gas cylinder.

[0040] In one embodiment, the divider 308 divides the placement plate 306 into four placement areas 304, each of which can hold one gas cylinder.

[0041] To facilitate airflow during vacuuming, it is further preferred that the placement plate 306 has several through holes 309 that penetrate the placement plate 306.

[0042] When in use, the arrangement of several through holes 309 facilitates the extraction of air from the lower end of the drying chamber 100 when the vacuum pump 102 is working, thereby facilitating the flow of air during vacuuming.

[0043] like Figures 3 to 4 As shown, in order to facilitate the installation or disassembly of the fixing bracket 303, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that there is an installation area 310 for installing the fixing bracket 303 between the pair of support parts 307. The bottom of the fixing bracket 303 is located in the installation area 310, and the two sides of the top of the fixing bracket 303 are detachably connected to the top of the pair of support parts 307 respectively.

[0044] Pin holes 311 are provided on both sides of the top of the fixing frame 303 and the top of the support part 307. The pin holes 311 penetrate the fixing frame 303 and the support part 307. A plug-in pin 312 is provided at the pin hole 311, and one end of the plug-in pin 312 can be inserted into the pin hole 311.

[0045] When in use, simply insert the bottom of the mounting bracket 303 into the mounting area 310, and then insert the plug pin 312 into the pin hole 311 on the mounting bracket 303 and the support 307 to fix the mounting bracket 303 to the mounting bracket 302; when it is necessary to disassemble and replace the mounting bracket 303, simply pull out the plug pin 312 to disassemble the mounting bracket 303.

[0046] like Figure 3As shown, in order to facilitate the sliding of the placement structure 301, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the sliding structure 300 includes a pair of slide rails 313 and a pair of sliders 314. The pair of sliders 314 are respectively disposed on the pair of slide rails 313 and are slidably connected to the slide rails 313. A pair of support parts 307 are respectively disposed on the pair of sliders 314 and are fixedly connected to the pair of sliders 314.

[0047] In use, the slider 314 and the slide rail 313 facilitate the sliding of the placement structure 301.

[0048] like Figure 2 , Figure 3 , Figure 5 As shown, in order to facilitate the support and placement of the structure 301, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that it also includes a telescopic support assembly 40. The telescopic support assembly 40 includes a mounting rail 400, a first sliding plate 401 and a second sliding plate 402. The mounting rail 400 is set at the bottom of the drying chamber 100 and is located between a pair of slide rails 313. The mounting rail 400 is provided with a sliding groove 403. The first sliding plate 401 and the second sliding plate 402 are set in the sliding groove 403 and are slidably connected to the mounting rail 400. One end of the first sliding plate 401 is provided with a mounting opening 404. One end of the second sliding plate 402 is set in the mounting opening 404 and is slidably connected to the first sliding plate 401. The other end of the second sliding plate 402 is detachably connected to the mounting frame 302 through a connector 50.

[0049] like Figure 4 As shown, the connector 50 includes a connecting rod 500, a connecting seat 501, and a locking block 502. The two ends of the connecting rod 500 are fixedly connected to the bottom of a pair of support parts 307 respectively. The connecting seat 501 is fixedly disposed at one end of the second sliding plate 402. The connecting seat 501 is provided with a slot that cooperates with the connecting rod 500. The locking block 502 is detachably connected to the connecting seat 501 by bolts. The connecting rod 500 can be placed in the slot and fixed by the locking block 502.

[0050] In use, the connecting rod 500 can be pulled by hand, causing the slider 314 to move on the slide rail 313, thereby pulling the placement structure 301 out of the drying chamber, which facilitates the placement of the gas cylinder. At the same time, after the placement structure 301 is pulled out, the first sliding plate 401, the second sliding plate 402 and the connecting seat 501 support the placement structure 301 to prevent it from tilting and facilitate the placement of the gas cylinder.

[0051] like Figure 4As shown, a further preferred embodiment is that the connecting rod 500 is provided with a pair of hand-held parts 503, which are sleeved on the connecting rod 500 and located on both sides of the connecting seat 501, and the hand-held parts 503 are provided with several grooves.

[0052] When in use, the grooves on the handle 503 can increase the friction between the hand and the handle 503, making it easier to pull the connecting rod 500.

[0053] like Figure 5 As shown, in a further preferred embodiment, the second sliding plate 402 is provided with a plug-in plate 405 at one end within the mounting port 404, and the first sliding plate 401 is provided with a plug-in groove 406. One end of the plug-in plate 405 is fixedly connected to the second sliding plate 402, and the other end can be inserted into the plug-in groove 406 and slidably connected to the first sliding plate 401.

[0054] In use, the plug plate 405 and the plug slot 406 can support the second sliding plate 402.

[0055] like Figure 3 As shown, a further preferred embodiment is that a limiting block 407 is provided at one end of the first sliding plate 401, and a limiting groove 408 is provided on the first sliding plate 401 to cooperate with the limiting block 407, and the limiting block 407 and the limiting groove 408 are slidably connected.

[0056] In use, the limiting block 407 can slide within the limiting groove 408. The limiting groove 408 can limit the maximum sliding distance of the first sliding plate 401 by limiting the maximum sliding distance of the limiting block 407, thereby controlling the maximum sliding distance of the slider 314, and finally limiting the maximum pull-out distance of the placement structure 301, thus avoiding the problem of the placement structure 301 falling off.

[0057] Working principle of this utility model:

[0058] In use, first place the fixing frame 303 on the mounting frame 302 so that the limiting ring 305 and the placement area 304 are engaged. Then, the bottom of the gas cylinder passes through the limiting ring 305 and is placed in the placement area 304 on the mounting frame 302, thus realizing the placement and positioning of the gas cylinder. At the same time, this utility model realizes the mobility of the placement structure 301 by setting the sliding structure 300, so that the gas cylinder can be placed on the placement structure 301.

[0059] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
